Description

Technical Field

[0001] This invention relates to the field of welding technology, and specifically to the configuration and usage method of a quick-clamping device for a switching type embedded wall valve. Background Technology

[0002] In the welding process, welding fixtures are needed to fix the workpiece on the machine tool and improve the welding accuracy and quality. Traditional welding fixtures often fix the workpiece directly to the fixture through threaded connections, which is simple in structure and provides relatively stable clamping effect.

[0003] However, for workpieces with different structures, welding fixtures with different structures are often required. (See attached image.) Figure 2 As shown, the prior art includes a switching type embedded wall valve 2, which includes a tubular vertical part 210, a bent part 220 protruding to the right from the bottom of the vertical part 210, and a pipe 230 hollowly disposed inside the vertical part 210 and the bent part 220; mounting feet are provided on the four corners of the switching type embedded wall valve 2, including a first mounting foot 211 and a second mounting foot 212 located on the left and right sides of the top of the vertical part 210, a third mounting foot 213 located on the left side of the bottom of the vertical part 210, and a fourth mounting foot 214 located on the right side of the bent part 220; the bottom ends of the first mounting foot 211 and the second mounting foot 212 are both inclined, and the two inclined surfaces of the first mounting foot 211 and the second mounting foot 212 combine to form a V-shaped structure; during the manufacturing process of the switching type embedded wall valve 2, a plug needs to be welded at the pipe opening of the pipe 230 located at the top of the vertical part 210.

[0004] For the switching wall-mounted valve 2, if the above-mentioned traditional welding fixture is used, the following problems exist: When fixing the switching wall-mounted valve 2 to the welding fixture, the first mounting foot 211 and the second mounting foot 212 need to be screwed to the welding fixture. However, since the first mounting foot 211 and the second mounting foot 212 are close to the pipe 230 on the vertical part 210, the threads on the bolts are easily burned and deformed under the high temperature of the welding torch, making it impossible to remove the switching wall-mounted valve 2 smoothly from the welding fixture. In addition, the installation and disassembly of the switching wall-mounted valve 2 requires repeated tightening of the bolts, which also makes the installation and disassembly of the switching wall-mounted valve 2 more cumbersome.

[0005] Existing technologies also include clamping welding fixtures, such as a welding fixture provided in an existing patent (application number: CN201710545752.X), which includes a base, a first clamping plate and a second clamping plate disposed on the base. In use, the clamp is first adjusted by adjusting the telescopic rod to roughly adjust the relative distance between the two clamping plates to a suitable position. Then, the adjusting bolt is adjusted to further fine-tune the distance between the two clamping plates, thereby stably clamping the workpiece between the two clamping plates. Therefore, there is no need to worry about the high temperature of the welding torch burning the fixture or the threads on the workpiece, and it will not affect the loading and unloading of the workpiece.

[0006] However, this solution has the following drawbacks: Since the welding joint is located at the top of the vertical part 210, in order for the welding wire to flow smoothly to every corner of the weld after melting, the pipe opening of the pipe 230 at the top of the vertical part 210 needs to be kept vertically upward, and the vertical part 210 needs to be kept vertical. Also, because the bottom of the switching embedded wall valve 2 is a slope, it is impossible to ensure that the vertical part 210 is in a vertical state when the switching embedded wall valve 2 is placed on the base. Before adjusting the bolt to shrink the clamping plate to hold the switching embedded wall valve 2, the vertical part 210 needs to be manually straightened, making the clamping and adjustment operation still inconvenient.

[0007] In summary, the main problem that needs to be solved is how to ensure that the clamping operation of the switching wall-mounted valve is simple and convenient while keeping the vertical part 210 in a vertical state. Summary of the Invention

[0008] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a configuration and usage method of a quick clamping device for a switchable wall-mounted valve. The device uses a V-shaped groove formed by the combination of a first and a second slot to engage the first and second mounting feet. Furthermore, an abutment member abuts against the lower part of the switchable wall-mounted valve. Thus, both the upper and lower sides of the switchable wall-mounted valve are clamped by the clamping device, ensuring the overall stability of the valve after installation and maintaining its vertical position. Moreover, the switchable wall-mounted valve can be directly inserted vertically into or removed from the clamping assembly, thereby completing the installation and removal operation of the switchable wall-mounted valve and significantly improving the convenience of installation and removal.

[0009] The effects of this invention are achieved as follows:

[0010] This application provides a configuration and usage method for a quick-clamping device for a switching type embedded wall valve, including the following steps:

[0011] I. Configuration of clamping device:

[0012] S11, prefabricated motherboard, with several first connection holes on the lower part of the front face of the motherboard, the first connection holes being configured to connect to the servo moving block on the machine tool;

[0013] S12, Install the snap-fit ​​assembly, which includes a first snap-fit ​​member, a second snap-fit ​​member, and at least one abutment member; the first snap-fit ​​member and the second snap-fit ​​member are disposed on the upper part of the front end face of the motherboard and are symmetrically arranged left and right; the first snap-fit ​​member is located on the left side of the motherboard and its top end is inclined to the lower right; the second snap-fit ​​member is located on the right side of the motherboard and its top end is inclined to the lower left; the top ends of the first snap-fit ​​member and the second snap-fit ​​member are respectively recessed with a first slot and a second slot, so that the first slot and the second slot combine to form a V-shaped groove; the abutment member is disposed on the front end face of the motherboard and is located below the first snap-fit ​​member and the second snap-fit ​​member;

[0014] II. Using a clamping device:

[0015] S21, the user holds the switchable wall-mounted valve and lifts it above the clamping device, aligning the first and second mounting feet on the vertical part with the first and second slots on the main board, respectively. Then, the user inserts the switchable wall-mounted valve into the clamping device from top to bottom, so that the V-shaped inclined first and second mounting feet can be engaged in the V-shaped groove formed by the combination of the first and second slots, thereby fixing the switchable wall-mounted valve and the clamping device relatively in the horizontal direction; and the lower part of the switchable wall-mounted valve abuts against the abutting part.

[0016] S22, the user releases the switchable wall-mounted valve. Under its own weight, the switchable wall-mounted valve can be stably locked into the first and second locking slots. The lower part of the switchable wall-mounted valve is abutted by the abutment, so it will not shake. This not only keeps the switchable wall-mounted valve fixed relative to the clamping device, but also keeps the vertical part vertical. Thus, the switchable wall-mounted valve is quickly clamped into the clamping device.

[0017] Furthermore, only one abutment is provided on the main board, and in step S21, the abutment is located below the first latching member. The switching wall-mounted valve has a tendency to move to the left. By providing an abutment support on the left side of the switching wall-mounted valve, the offset can be effectively prevented, which not only saves the manufacturing cost of the clamping device, but also reduces the overall weight of the clamping device.

[0018] Furthermore, the right side wall of the abutment is inclined downwards to the right, and the right side wall of the abutment is configured so that the center line of the vertical part and the center line of the main board coincide. In step S21, the third mounting foot abuts against the right side wall of the abutment. This allows the third mounting foot to abut against the abutment more naturally and stably, and ensures that the vertical part remains vertical.

[0019] Furthermore, the first slot has an inclination angle of 10-40° relative to the horizontal plane, and the second slot has an inclination angle of 20-50° relative to the horizontal plane. The inclination angles of the first and second slots are consistent with the inclination angles of the first and second mounting feet, which allows the switching wall-mounted valve to be more stably engaged with the engagement assembly and is less prone to shaking.

[0020] Furthermore, the first and second slots have L-shaped cross-sections, allowing the bottom surface of the switching wall-mounted valve to be in close contact with the front end of the main board in step S21. This prevents the switching wall-mounted valve from wobbling back and forth relative to the main board, further improving the stability of the connection between the switching wall-mounted valve and the snap-fit ​​assembly.

[0021] Furthermore, the top of the main board is recessed inward to form a relief opening. In step S21, after the switchable wall-mounted valve is installed on the clamping device, the top of the vertical part is exposed to the clamping device through the relief opening, so that multiple welding torches can be evenly arranged around the pipe for welding.

[0022] Furthermore, the motherboard has a through-hole cutout in the middle, with reinforcing ribs separating the upper end of the through-hole from the lower end of the clearance opening. This facilitates heat dissipation for the motherboard while reducing the overall weight of the clamping device.

[0023] Furthermore, a mounting groove is recessed inward at the lower part of the front face of the motherboard, and the first connection hole is set in the mounting groove. The mounting groove is configured to snap onto the servo moving block on the machine tool. By snapping the servo moving block into the mounting groove, the connection between the servo moving block and the motherboard is made more stable.

[0024] The configuration and usage method of the quick clamping device for the switchable wall-mounted valve provided in this application utilize a V-shaped groove formed by the combination of a first and a second slot to engage the first and second mounting feet. This allows the upper part of the switchable wall-mounted valve to be stably installed on the clamping device. Furthermore, the abutment member abuts against the lower part of the switchable wall-mounted valve, preventing the lower part of the valve from swinging to the left due to its own weight imbalance. Thus, both the upper and lower sides of the switchable wall-mounted valve are clamped by the clamping device, ensuring the overall stability of the valve after installation and maintaining a vertical position. Although the horizontal movement of the switchable wall-mounted valve is restricted after installation on the clamping device, it can still move vertically upwards, thereby directly achieving the purpose of detaching it from the clamping device. The installation operation can be completed simply by aligning the switchable wall-mounted valve with the engaging component and inserting it vertically downwards. Therefore, the installation and disassembly of the switchable wall-mounted valve is very simple and convenient. Attached Figure Description

Detailed Implementation

[0038] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0039] Please refer to the attached document. Figure 1-11 This application provides a configuration and usage method for a quick-clamping device for a switchable embedded wall valve, including the following steps:

[0040] I. Configuration of clamping device:

[0041] S11, prefabricated motherboard 1, the lower part of the front end face of motherboard 1 is provided with a plurality of first connection holes 101, the first connection holes 101 are configured to connect to the servo moving block on the machine tool;

[0042] S12, install the snap-fit ​​assembly, which includes a first snap-fit ​​member 110, a second snap-fit ​​member 120, and at least one abutment member 130; the first snap-fit ​​member 110 and the second snap-fit ​​member 120 are disposed on the upper part of the front end face of the motherboard 1 and are symmetrically arranged left and right; the first snap-fit ​​member 110 is located on the left side of the motherboard 1 and the top of the first snap-fit ​​member 110 is inclined to the lower right; the second snap-fit ​​member 120 is located on the right side of the motherboard 1 and the top of the second snap-fit ​​member 120 is inclined to the lower left; the tops of the first snap-fit ​​member 110 and the second snap-fit ​​member 120 are respectively recessed with a first slot 111 and a second slot 121, such that the first slot 111 and the second slot 121 combine to form a V-shaped groove; the abutment member 130 is disposed on the front end face of the motherboard 1 and is located below the first snap-fit ​​member 110 and the second snap-fit ​​member 120;

[0043] II. Using a clamping device:

[0044] S21, the user holds the switchable wall-mounted valve 2 and lifts it above the clamping device, aligning the first mounting foot and the second mounting foot on the vertical part 210 with the first slot 111 and the second slot 121 on the main board 1, and then inserts the switchable wall-mounted valve 2 into the clamping device from top to bottom, so that the V-shaped inclined first mounting foot 211 and the second mounting foot 212 can be inserted into the V-shaped groove formed by the combination of the first slot 111 and the second slot 121, so that the switchable wall-mounted valve 2 and the clamping device are relatively fixed in the horizontal direction; and the lower part of the switchable wall-mounted valve 2 abuts against the abutment member 130;

[0045] S22, the user releases the switching wall-mounted valve 2. Under its own weight, the switching wall-mounted valve 2 can be stably locked into the first slot 111 and the second slot 121. The lower part of the switching wall-mounted valve 2 is abutted by the abutment member 130 so that it will not shake. This not only keeps the switching wall-mounted valve 2 fixed relative to the clamping device, but also keeps the vertical part 210 in a vertical state. Thus, the switching wall-mounted valve 2 is quickly clamped into the clamping device.

[0046] In this embodiment, the V-shaped groove formed by the combination of the first slot 111 and the second slot 121 engages the first mounting foot 211 and the second mounting foot 212, thereby allowing the upper part of the switching wall-mounted valve 2 to be stably installed on the clamping device. Furthermore, the abutment member 130 abuts against the lower part of the switching wall-mounted valve 2, preventing the lower part of the switching wall-mounted valve 2 from swinging to the left due to its own unbalanced weight. Thus, both the upper and lower sides of the switching wall-mounted valve 2 are clamped by the clamping device, ensuring that the switching wall-mounted valve 2 remains stable after installation, and the vertical part 210 remains in a vertical position. Although the horizontal movement of the switching wall-mounted valve 2 is restricted after installation on the clamping device, it can still move vertically upwards directly, thereby achieving the purpose of directly removing it from the clamping device. The installation operation can be completed simply by aligning the switching wall-mounted valve 2 with the engaging component and inserting it vertically downwards. Therefore, the installation and disassembly operation of the switching wall-mounted valve 2 is very simple and convenient.

[0047] The motherboard 1 has two first connection holes 101 on the lower part of its front end face. The motherboard 1 is threadedly connected to the servo moving block on the machine tool through the first connection holes 101. By connecting the motherboard 1 to the servo moving block of the machine tool, the clamping device can automatically move in and out of the welding operation with the servo mechanism, improving the convenience of the welding operation. Furthermore, the threaded connection fixes the motherboard 1 and the servo moving block, ensuring a stable connection and facilitating the loading and unloading of the clamping device.

[0048] Preferably, the snap-fit ​​assembly is connected to the motherboard 1 via a threaded connection. The first snap-fit ​​member 110 has two second connection holes 112, through which it is screwed to the motherboard 1. The second snap-fit ​​member 120 has two third connection holes 122, through which it is screwed to the motherboard 1. The abutment member 130 has two fourth connection holes 131, through which it is screwed to the motherboard 1. The threaded connection provides sufficient connection strength while facilitating the installation and removal of the snap-fit ​​assembly. Of course, in other embodiments of this application, the connection between the snap-fit ​​assembly and the motherboard 1 can also be welding, snap-fitting, etc.

[0049] In some embodiments of this application, only one abutment 130 is provided on the motherboard 1, and in step S21, the abutment 130 is located below the first snap-fit ​​member 110.

[0050] In this embodiment, since the bent portion 220 protrudes to the right relative to the vertical portion 210, when the vertical portion 210 is kept vertical, the weight on the right side of the switching wall-mounted valve 2 is heavier. In order to maintain balance, the switching wall-mounted valve 2 tends to move to the left. Therefore, by simply providing an abutment 130 below the first latching member 110, the left side of the switching wall-mounted valve 2 is supported by the abutment 130 when the switching wall-mounted valve 2 is installed in the clamping device, which can effectively prevent the switching wall-mounted valve 2 from shifting to the left and keep the vertical portion 210 in a vertical state. This not only saves the manufacturing cost of the clamping device, but also reduces the overall weight of the clamping device.

[0051] In some embodiments of this application, the right side wall of the abutment 130 is inclined downwards to the right, and the right side wall of the abutment 130 is configured such that the center line of the vertical part 210 and the center line of the main board 1 are aligned. In step S21, the third mounting foot 213 abuts against the right side wall of the abutment 130. When the switching wall-mounted valve 2 is installed on the clamping device, the third mounting foot 213 located on the bottom left side of the switching wall-mounted valve 2 abuts against the right side wall of the positioning member 130, so that the lower part of the switching wall-mounted valve 2 is supported and the vertical part 210 remains vertical. Because the right side wall of the positioning member 130 is inclined, the third mounting foot 213 is less likely to slide on the side wall when it abuts, so that the third mounting foot 213 can abut against the positioning member 130 more naturally and stably.

[0052] In some embodiments of this application, the first slot 111 has an inclination angle of 10-40° relative to the horizontal plane, and the second slot 121 has an inclination angle of 20-50° relative to the horizontal plane. The inclination angles of the first slot 111 and the second slot 121 are consistent with the inclination angles of the first mounting foot 211 and the second mounting foot 212, so that the shape of the V-groove fits into the shape of the two mounting feet on the left and right sides of the main body 210, thereby enabling the switching wall-mounted valve 2 to be more stably engaged with the engagement assembly and less prone to shaking.

[0053] In some embodiments of this application, the first slot 111 and the second slot 121 have an L-shaped cross-section, so that in step S21, the bottom surface of the switching wall-mounted valve 2 can be tightly attached to the front end surface of the main board 1. This prevents the switching wall-mounted valve 2 from wobbling back and forth relative to the main board 1, further improving the stability of the connection between the switching wall-mounted valve 2 and the clamping device.

[0054] In some embodiments of this application, the top of the main board 1 is recessed inward to form a relief opening 140. In step S21, after the switchable wall-mounted valve 2 is installed in the clamping device, the top of the vertical part 210 is exposed to the clamping device through the relief opening 140.

[0055] In this embodiment, in order to ensure uniform welding, when welding the switching wall-mounted valve 2, seven welding torches need to be evenly arranged around the pipe opening of the upper end of the vertical part 210 and welded simultaneously. Therefore, it is necessary to avoid the welding torches being blocked by the main board 1. By recessing the relief opening 140 at the top of the main board 1, the pipe 230 at the upper end of the main body 210 is exposed to the clamping device, so that multiple welding torches can be evenly arranged around the pipe opening of the pipe 230 for welding, effectively avoiding problems such as overheating of the front end, overheating and burning of the threads, and poor welding of the rear end caused by inconsistent flame coverage.

[0056] In some embodiments of this application, the motherboard 1 has a through hole 150 in the middle, and the upper end of the through hole 150 and the lower end of the clearance opening 140 are separated by a reinforcing rib 141.

[0057] In this embodiment, by setting through holes 150, the heat generated during the welding of the switching wall-mounted valve 2 can be dissipated through the through holes 150, effectively preventing the main board 1 from overheating and deforming due to excessive heat in the switching wall-mounted valve 2; in addition, the hollowing out of the main board 1 can reduce the overall weight of the clamping device and reduce the load on the machine tool.

[0058] During the welding process, the clamping device softens under high temperatures. Because the switching wall-mounted valve 2 is relatively heavy, the two sides of the clamping device at the slot are thin and have low strength, making them prone to deformation under pressure. Therefore, the through hole 150 and the clearance opening 140 are separated by a reinforcing rib 141. The two ends of the reinforcing rib 141 connect to the left and right sides of the slot on the main board 1, thereby strengthening the main board 1 and preventing it from deforming after heating.

[0059] Of course, in other embodiments of this application, when the clamping device is used to clamp other lighter workpieces, the through hole 150 and the clearance opening 140 may not be separated by a reinforcing rib 141, so that the through hole 150 and the clearance opening 140 are connected into a slot, thereby further reducing the overall weight of the clamping device and reducing the load.

[0060] In some embodiments of this application, the lower part of the front end face of the motherboard 1 is recessed inward to form a mounting groove 160, and the first connection hole 101 is disposed in the mounting groove 160. The mounting groove 160 is configured to snap onto the servo moving block on the machine tool. By snapping the servo moving block into the mounting groove 160, the connection between the servo moving block and the motherboard 1 is made more stable, and the clamping device is prevented from falling off the servo moving block due to unstable connection.
